CHONBURI, Thailand (AP) -- Defending champion Amy Yang carded a 3-under 69 to lead by one halfway through the LPGA Thailand on Friday.
Yang trailed first-round leader Lexi Thompson by two before teeing off at Siam Country Club, then had consecutive bogeys on Nos. 5 and 6, but rallied with four birdies, including on the par-3 12th.
At 9 under overall, the South Korean was one shot ahead of countrywoman Q Baek (71) and Americans Jessica Korda (66) and Thompson (72).
''I struggled a little bit on the front, two bogeys straight, but I stayed patient, got through it well,'' Yang said.
